Melody from LH83/19 and rsigns from LH83
wrong syllabes: a-do-re-mus
Corrected syllabification and removed initio debilis
Added one episema: H has a pes quadratus for 0624I which has the same melody.
@iaquobus: Liber Hymnarius always spells ad-o-re-mus, so I will standardize all the invitatories to that.
NABC is from "Regem præcursoris", the single word that differs is indicated in brackets
